Abstract

Objective: The objective of this study was to describe the posture patterns of adolescents diagnosed with adolescent idiopathic scoliosis (AIS) in a scoliosis school screening (SSS). Methods: Two-dimensional photogrammetry was used to assess the posture of 37 adolescents diagnosed with scoliosis (scoliosis group, SG) (Cobb angle >= 10 degrees) and 76 adolescents with a false positive diagnosis (false positive group, FPG) (Cobb angle <10 degrees, angle of trunk rotation >= 7 degrees). In total, 2562 10-to 14-year-old adolescents were enrolled in the SSS, which was performed in public schools in the cities of Amparo, Pedreira, and Mogi Mirimin the state of Sao Paulo, Brazil. Their posture was analyzed using Postural Analysis Software. Continuous variables were tested using Student t test, and categorical variableswere tested using a chi(2) test. The SG, FPG, simple curve group, and double curve groupwere all compared. Bivariate analysis was used to identify associations between postural deviations and scoliosis. The adopted significance level was alpha = .05. Results: The SG (2.7 +/- 1.9 degrees) had greater shoulder obliquity than the FPG (1.9 +/- 1.4 degrees) (P = .010), and this deviation was associated with scoliosis (odds ratio {[}95% CI] P = 1.4 {[}1.1-1.8] 0.011). The SG had asymmetry between the right-and left-side lower limb frontal angle, shoulder sagittal alignment, and knee angle. The double curve group (3 +/- 1.7 degrees) presented a greater value of the vertical alignment of the torso than the simple curve group did (1.9 +/- 1 degrees; P = .032). Conclusions: Adolescents diagnosed with AIS in an SSS had greater shoulder obliquity and asymmetry between the right and left sides. Shoulder obliquity was the only postural deviation associated with AIS. (AU)
